Abstract
The invention relates to a water-cooled low-noise pump. A pump cover is arranged on a pump body and is connected with a lower end cover arranged at the upper end. A motor casing is arranged on the lower end cover. An upper end cover is arranged on the motor casing. An integrated shaft is arranged in the middle of the pump body. An impeller is mounted at one end of the integrated shaft, and the other end of the integrated shaft is connected with the upper end cover. A bearing cooling cavity is formed by the upper end cover and an end cover. A wiring board is arranged in the bearing cooling cavity. A motor stator/rotor is arranged between the upper end cover and the lower end cover. A cooling jacket is arranged on the outer surface of the motor casing. Pipelines are arranged at the water inlet flange end and the water outlet flange end and are connected with the cooling jacket. A motor is cooled through self-circulating water of the pump instead of a fan; the cooling effect is good, noise is low, and the service life of the motor is prolonged; the occupied area is greatly reduced; investment of capital construction is saved; the motor and the pump are coaxial, and thus an intermediate connecting structure is simplified; in addition, the impeller has high dynamitic and static balance, in this way, operation is stable and reliable, vibration is small, and noise is low; installation is convenient, leakage is avoided, and applicability is high.
